This guy is Quazi Mohammad Rezwanul Ahsan Nafis, a 21-year-old Bangladeshi student who traveled to the United States with the intention of carrying out a major terrorist attack. He wanted to blow up this building, 33 Liberty Street, the home of the Federal Reserve Bank located in the heart of the New York City's Financial District.

Fortunately, the FBI knew about his intentions and set him up to fail, arresting him after he tried to detonate a 1,000-pound bomb this morning. A bomb made with fake explosives facilitated by undercover FBI agents.

Back when he came up in January, he started to recruit people to help him with the attack. He contacted a covert FBI agent posing as an Al Qaeda operative. Nafis told him that he wanted to carry out a major attack against an iconic building in New York CIty:

I don't want something that's like, small. I just want something big, something very big. Very very very very big, that will shake the whole country.

After deciding the target, the agent facilitated him twenty 50-pound bags of fake explosives. Nafis then proceeded to buy all the electronic and mechanical components needed to build the bomb. According to U.S. Attorney Loretta Lynch:

The defendant came to this country intent on conducting a terrorist attack on U.S. soil, and worked with single-minded determination to carry out his plan. The defendant thought he was striking a blow to the American economy. He thought he was directing confederates and fellow believers. At every turn, he was wrong, and his extensive efforts to strike at the heart of the nation's financial system were foiled by effective law enforcement.

This morning, together with the undercover FBI agent, they parked a van carrying the fake bomb at 33 Liberty Street. After recording a video in which he claimed that they "will not stop until [they] attain victory or martyrdom," Nafis tried to detonate the bomb. At that point, the agents arrested him.

According to the FBI, this has been the 15th thwarted terrorist plot since September 11. [CBS NY]
